Improving Africa’s soils to cut emissions and boost food security

On Carbon Brief, 2 August 2017 Dr Keith Shepherd is a principal soil scientist at the World Agroforestry Centre (ICRAF) and Dr Rolf Sommer is a principal soil and climate change scientist at the International Center for Tropical Agriculture (CIAT). Together they lead the Restoring Degraded Landscapesresearch theme of the CGIAR Research Program on Water, Land and Ecosystems (WLE). How we manage soils is crucial to tackling climate change. …

Air pollution and dust can cut solar panel performance by 20-25%

By James Ayre, Clean Technica, 28 June 2017 A new study has now quantified the solar cell energy output loss occurring around the world as a result of air pollution and dust — bringing one of the most serious limitations of solar photovoltaic reliance in the more polluted parts of the world to the forefront, and giving us a better …

Warming soils releases more and absorbs less CO2 than previously thought

By James Ayre in Clean Technica, 13 March 2017  As the world’s soils continue warming over the coming decades and centuries, they could release much higher levels of carbon dioxide than was previously thought, according to new research from the US Department of Energy’s Lawrence Berkeley National Laboratory. The research is apparently some of the first (or the first) to …

Talk about the weather

By HIROKO TABUCHI 28 Jan 2017, New York Times GLEN ELDER, Kan. — Doug Palen, a fourth-generation grain farmer on Kansas’ wind-swept plains, is in the business of understanding the climate. Since 2012, he has choked through the harshest drought to hit the Great Plains in a century, punctuated by freakish snowstorms and suffocating gales of dust. His planting season starts …

Global study finds soil carbon losses will be greatest in world’s coldest places: melting tundra is biggest threat, might equal all of US emissions

Cross-posted from Science Daily, November 30, 2016  For decades, scientists have speculated that rising global temperatures might alter the ability of soils to store carbon, potentially releasing huge amounts of carbon into the atmosphere and triggering runaway climate change. Yet thousands of studies worldwide have produced mixed signals on whether this storage capacity will actually decrease — or even increase — …

Soil Carbon Capture: Great Loamy Hope Or Bandaid?

Cross-posted from Clean Technica, December 17th, 2016 by Michael Barnard  Recently on Quora I was challenged to assess the likely capacity of soil carbon sequestration approaches (sometimes referred to as biological carbon capture and sequestration or BCCS) by a researcher in the space. The premise was that two thirds of the carbon which had been sequestered in the soil had been lost …

Climate mitigation hope through better soil carbon management

CREDIT: SHUTTERSTOCK Climate change is a massive problem with the potential to completely reshape the world, both literally (with rising sea levels and melting glaciers) and figuratively (with the way we grow food, or the way that we handle allergies). And while the consequences caused by climate change could be huge, the solutions — transitioning to a completely fossil fuel-free …
